I can see how it will have excellent specs and is a neat way to make a regulator.

I was lucky enough to be able to try out the new 78SPX Bellesons in my
DAC. I have to say that for some time, I started using the belleson regulators in
my projects and this has produced a leap forward in the quality of the sound.

I used the spx78 to feed a pair of PCM1704 in a self-built dac based on a
jlsounds conversion board (powered with the belleson spj). with IV
conversion made by a resistance and valve output stage. The spx, have replaced a
pair of belleson SPM. I was amazed at having further increased some parameters.
If in this position, the simple regulators lm78xx are inserted, the sound
becomes mechanical and "raw", with the 78spm, magic comes into play,
everything becomes clear, smooth, sweet, dynamic, and a lot of
unimaginable micro detail. As soon as I mounted the spx, I was amazed. They
may seem to be wasted where they need a few mw of power but in addition to
keeping all the positive aspects that were introduced by the SPM, have given
more control and energy to the sound message.

I can conclude by saying thank you to Belleson that allowed me to
get a preview of these jewels, The power supplies are often not considered but
in reality they are the first brick of the sound chain.

Thanks again Belleson, Fabio Di Pietro.

I have tried some simple switching supplies and a small bench linear supply, but past experience has taught me that a linear with the Jung style regulators and Cree rectifiers are much better. Your devices used in my power supplies performed extremely well and I am very please by their performance.

Both supplies working together for the PI and hat have elevated the performance to a large degree! Kudos to a great product in a small and easy to use package.

I changed only the orginal Regulator in my Singxer SU-1 DDC with the SPZ 5V. The improvement is really Great! All is better. Dynamics, Bass, Stage. The Sound is much more stable, more Highend. Absolutely Great.

Then I change in my Power-Supply with a LT1084 only the Regulator with a SPZ17. This will supply my DAC. Great Update. More stable, fast and clean Sound with great Balance, with much more clean Air in the Sound.

I have tried the SPZ behind a LifePo4 Accu. The Sound with a TPS7A4700 was dead, no musical. With the SPZ there is more Air, more Music, enhanced dynamic and speed. A great update.

I already have one of you regs 3.3V/500mA and 5V/2A. I was impressed with 3.3V version.
I used it for powering the clock. It beats some of shunts I tried at this position.
I consider them as good as best shunt I have.

Check out this beautiful handcrafted work! It uses SPHP for filament power.

As always thanks for all your consideration....you make an awesome product and have incredible
customer service,

Igor replaced all regulators on his Metrum Acoustics DAC. They are mounted on a mezzanine
board and wired to the main board. He said "I am finished the tweak already. All the good!"

The Belleson regulators that I put in my Universal Audio Urei 1176 are fantastic!
The noise is lowered by about 4dB ... and the response in my opinion is faster and it has more low end.

March 10, 2014 Bart T, NJ USA

I use belleson 3.3v to feed oscillators in my oppo 95 player and SP +/- 15v in Musical Fidelity X-LPS v8 phono with great results. Just installed the [new] regs in place [in Musical Fidelity 750K input section]. I'm quite pleased with result. :-)

February 2, 2014 Matt, USA

i did some measurements with a low end usb adc which is enough to show differences in mods. saw a ~6db improvement in noise floor and imd dropped by 50%. this was from "low noise" mc7812/mc7912 and an ams 1117 5v.

[After 6 weeks of support over email to help a complex install] you are great!!! All the positive reviews are certified to the power of "n".
Overall, a very large increase in sound quality, dynamics, better bass gradation etc. Now sound is better than the first day. For me, the most valuable is the Superpower brings music from the background. Everything is smooth with finesse and a sense of harmony. The good thing is that there is no compression, which interferes with the presentation of music and instruments, you can hear the natural sounds of different instruments.

i use it for my nas server the output voltage svings 11,97 – 11,98. the bass is more tight and deep, and there is more control...

December 16, 2013 Sunny Chan

Just installed the SPHV to my [preamp] using a CLCRC power that I have changed it to C SPHV C configuration. However, I don’t have sufficient vocabulary to describe it
1. The background is quieter.
2. The low and high are extended
3. More details
4. Higher density

I am totally amazed by the improvement that it brings to my preamp. Thanks a lot.

November 13, 2013 Sunny Chan

I am already a Belleson user that I am using your standard 0.5A version for my phono amp drawing 0.4A with very good result. I used to use [competitor] but Belleson gives much better resolution.

August 21,2013 Jeff Hazlett [TX USA]

Yet again the SPL17 sounds great! This one went into a phono pre-amp. Once again I thank you for the marvelous support. This is the 4th audio component that I've installed your regulators in and every one of them sounds great!

April 3, 2013 Jeff Hazlett [TX USA]

Just wanted to say thanks again for all the support. I sitting here listening to music and being thrilled by the improvement your Super Regulators have provided. I've preformed many mods but this is the best bang for the buck by far!!

March 21, 2013 John Makela [CA USA]

...there certainly are more dynamics, more stage depth and a smoother (in a good way) sound.
Thank you for all the help.

It’s amazing how much the sound quality
improved when I just did the DAC on the [Schiit] BiFrost with a superpower
regulator. November 2, 2012: Thank you for all of your help. You have a customer for life
and I will recommend your product [to] whoever is interested in modifying their electron[ic]s.

July 10, 2012 Carlo Hart [Italy]

this is a huge improvement over the original 7805 and a few step over the
newclassd regulator.

June 13, 2012 Mike [Malaysia]

I installed the Superpowers into the DAC, and been listening to music for hours and hours.
Ok, I am a believer in the Superpower regs :)

March 2012 Wayne Mastel [ND USA]

[comments from Belleson] Wayne has done some awesome work!
In March he completed his McIntosh preamp upgrade
including 3 SPHV regulators for the tube section and 5 SPJ
regulators for the solid state sections.

The C2300 full view, see SPJ in left foreground and 1 SPHV
mounted right center on a heat sink, mostly hidden by 2 capacitors.

i have bought many of your regulators, i must say i have never heard such a sound quality. unbelievable.

January 18, 2012 Jonathan Parle [NSW Australia]

I have been incredibly impressed with these regulators – not just for this
Heed project, but also the previous ones I purchased to build power supplies
for my two Project DAC Box USB devices. I am so impressed that I will now
only purchase audio components that I can adapt so as to be powered using these super regulators...
Your service is excellent too.

I am a happy customer just wanting to make a compliments to your latest superpower
regulator. I replace the [competitor] regulator with your reg which is powering the DAC
section. For the first note from my sacd player, I can hear mark improvement in
terms of low level information retrieval, the coherance of the music, the
stability of the sound stage, and what's more important is music flows naturally
with vast dynamics. The last one is an utmost achievement that any audiophile
strive to achieve because most of the time we get music flow but sacrifices a
little bit of dynamic or vice versa. This time the superpower hit two birds with
one stone...This is truly an amazing experience for me.

First off thanks for developing the Superpower regs, so far I have implemented
the +5V and +12V versions in my CMP transport and DIY-DAC (Analog AD1852) as
digital supplies. Sound improvement is stunning – in audiophile terms the bass
impact, sound stage, reverb tails are the qualities that have improved the most.
You get the feeling that your ear is so close to the mastertape rolling by the
tape heads, it gets spooky! ;)

April 6, 2011 Laurent Tay [Singapore]

I used the pair on my Audio Note Pre-amp, and the result is stunning!
The pair brings a clean and quiet black background...after I tried some
of your superb regulators, there's no going back!

January 21, 2011 Mario Beichel

Looking forward to the superregulators (I also highly recommend them to my audio friends :))

January 12, 2011 A. Shan [Hong Kong]

Sonically, I think my modded Transporter can really run with the big guns now
(ie: expensive CD transports in the US$10K price range). The low jitter
clocks I used (0.36ps) really demand the clean output of superpower to perform
at their best...Many thanks for coming up with this innovative circuit.

October 12, 2010 Tin Onn Lee [Singapore]

Superpowers to replace 14 monolithic regulators in a Naim SuperCap
power supply. This shows 1 of 7 heat sinks, each of which contains 2 regulators.

June 29, 2010 Larry Ho [CA USA]

Technical information and communication: Simply the best!

Product performance: Performed like in the specifications.

Sound: Dynamics is superb. Both in macro and micro dynamics. Also, noise free.

Overall: Will use it again!

Finally got the cd player modded with the superpowers! I am
speechless. Really jaw dropping improvement.
It's like a thick veil lifted with extended frequencies top and bottom.
Music now becomes a lot more intense
and emotional and I simply can't stop spinning disc after disc. The
extra details that I hear are staggerring!...Once again
thanks for all the support you have given and also for coming out with
such great product. I am thoroughly impressed!
Pictures to come later . Too occupied with music. :-)

May 9, 2010 Michel C. [Montréal Canada]

Thanks for the detailed explanation - I appreciate the good service.

April 15, 2010 A. Shan [Hong Kong]

May I say that your support is second to none. Absolutely first
rate. I'm glad that I went with your product.

April 13, 2010 A. Shan [Hong Kong]

It is powering my digital reclocker. There is an improvement in
sound (better image/focus, and more detailed)...I'm pleased
with it and your service.

"I changed the power regulator +5 volts for the DAC section to a
Belleson super regulator which cost me about 53 euro shipped from
parts connexxion in canada. When i heard it first time with the
new regulator i couldnt believe how good the sound was. Instruments
more defined, voices also, better soundstage and also the bass.
Much more enjoyable."
